<p>This module defines classes which implement the client side of the HTTP and

<div class="admonition note">
<p class="first admonition-title">Note</p>
<p class="last">The public interface for this module changed substantially in Python 2.0.  The
<tt class="xref py py-class docutils literal"><span class="pre">HTTP</span></tt> class is retained only for backward compatibility with 1.5.2.  It
should not be used in new code.  Refer to the online docstrings for usage.</p>
</div>
<p>The module provides the following classes:</p>
<dl class="class">
<dt id="httplib.HTTPConnection">
<em class="property">class </em><tt class="descclassname">httplib.</tt><tt class="descname">HTTPConnection</tt><big>(</big><em>host</em><span class="optional">[</span>, <em>port</em><span class="optional">[</span>, <em>strict</em><span class="optional">[</span>, <em>timeout</em><span class="optional">[</span>, <em>source_address</em><span class="optional">]</span><span class="optional">]</span><span class="optional">]</span><span class="optional">]</span><big>)</big><a class="headerlink" href="#httplib.HTTPConnection" title="Permalink to this definition">¶</a></dt>
<dd><p>An <a class="reference internal" href="#httplib.HTTPConnection" title="httplib.HTTPConnection"><tt class="xref py py-class docutils literal"><span class="pre">HTTPConnection</span></tt></a> instance represents one transaction with an HTTP
server.  It should be instantiated passing it a host and optional port
number.  If no port number is passed, the port is extracted from the host
string if it has the form <tt class="docutils literal"><span class="pre">host:port</span></tt>, else the default HTTP port (80) is
used.  When True, the optional parameter <em>strict</em> (which defaults to a false
value) causes <tt class="docutils literal"><span class="pre">BadStatusLine</span></tt> to
be raised if the status line can&#8217;t be parsed as a valid HTTP/1.0 or 1.1
status line.  If the optional <em>timeout</em> parameter is given, blocking
operations (like connection attempts) will timeout after that many seconds
(if it is not given, the global default timeout setting is used).
The optional <em>source_address</em> parameter may be a tuple of a (host, port)
to use as the source address the HTTP connection is made from.</p>
<p>For example, the following calls all create instances that connect to the server
at the same host and port:</p>
